Screamin' Eagle Smart Tune Pro Auto Tuning Module

Like to get some input on the SE Smart Tune Pro Auto Tuning Module with the wideband O2 sensors. I've completed a Stage II update on my M8 Ultra and I'm considering adding the Smart Tune module. Any Pro's or Con's with this addition.

My dealer advised that unless I was going to be traveling through altitude changes, or adding engine components (i.e. stage III or IV), that I wouldn't really see much gain out of the auto-tune. The tune that they have put into the ECM works just fine. However, if you're planning to add accessories down the road or you're a traveler, it might be the right ticket for you!!

I thought that was pretty solid advice as I've had very few dealers EVER tell me they didn't want to take my money!!

I am going to follow this tread as I too am thinking about purchasing this tuner for a Stage I build which will lead to a Stage II. I have acquired the SE Street Cannons and am looking for a SE Air Cleaner. I am also shopping for a Windows 10 PC for the tuner as I use Apple at the tuner is not compatible. I have found some really nice PC's for 134 shipped which will work. Please continue to post your experience with the tuner.

Its still just more EPA approved smoke and mirrors.


If you want a true auto tuner free of the EPA strings and limits, look at something like a Thundermax.

I have been wondering about them as well. I hear that it does not have near the control that the aftermarket tuners have.

I have a SE Pro on a family members 16' Tri-Glide. It works as advertised and as it's already been said- there isn't a need to move into the Auto Tune arena from SE unless you're doing a lot of traveling that has altitude changes, or you plan to add engine parts down the road. The standard SE tune will do just fine.

Think of it this way- the SEPT is double the cost of the standard tuner- so if you plan to add it now and only do (1) more engine upgrade, you're better off with the standard tuner and just pay a minimal cost to have them load the tune. If you go to the SEPT, you'll not only pay double for the tuner (You're still buying the standard tuner that actually loads the tune AND then the additinoal Auto Tune module that stays on the bike), but you'll also pay additional labor charges if your pipes need to be drilled out for the larger sensors going into the bike.

My closest HD dealer dyno tunes and strongly sways people away from the SE tuners and prefers the Dyno-Jet modules. As also pointed out, due to EPA restrictions, the SE tuners do not have the same flexibility to "dial in" the tune for your bike. If a fuel ratio needs to move +/- 8 points, the Dyno-Jet or other reputable tuners will allow you to do that... however, due to the EPA settlement with the MotorCo, the SE tuners might only allow you to move a maximum of +/- 4 points- so there is the potential that you're not going to really run at the optimum level for your particular set up using SE tuners.

Good luck and let us know what you decide!

I am aware of all the epa vs aftermarket tuner debate. My 16 has a Power Vision and was dyno tuned by one of the best. I am just thinking about my 7 year warranty that I have on the 114 stage 3 kit that was installed on del of the bike. 104/106 is what the motor made with the SEPST. Obviously there is a ton more potential in this set up with an aftermarket tuner. Once I go down that road I might as well go to Fuel Moto and have the 120 installed with the Power Vision tuner. Some people think warranty is not important. With all the problems the M8 has been having I think I will keep the Warranty for a few years before I dig down deeper for real HP.

I had the smart tune pro installed and let me tell you it is worth it if your wanting to stay with the SE tuner for warranty. The bike runs way better idles better and is very well behaved at slow speeds now. With the SEPST only download it ran like shit. Now all is good !

Hold up on the all is good with the Smart tune pro. Took a 1000 mile trip this weekend and the motor was pining constantly going down the interstate. Called dealer ship and they say it was because it was to hit out. Lol so the bike can’t be rode when it’s hot out. What a joke.
